<p class=MsoNormal>Hello IronPython Community,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m pleased to announce the release of IronPython
1.1.2 RC1. In this release twenty-one CodePlex work Items that were identified
as high priority on the IronPython mailing list were fixed. It’s
worth noting that this included the implementation of the “_winreg”
CPython module and a few performance improvements in targeted areas. Please
also note that there are two potentially breaking changes in this release:<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;line-height:normal;
mso-list:l0 level1 lfo2'><![if !supportLists]><span style='font-family:Symbol'><span
style='mso-list:Ignore'>·<span style='font:7.0pt "Times New Roman"'>
</span></span></span><![endif]>nt.unlink will now throw an exception if the
file doesn’t exist, as it does in CPython.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;line-height:normal;
mso-list:l0 level1 lfo2'><![if !supportLists]><span style='font-family:Symbol'><span
style='mso-list:Ignore'>·<span style='font:7.0pt "Times New Roman"'>
</span></span></span><![endif]>The signature of
IronPython.Runtime.Operations.Ops.Id() has changed and it now returns an object
instead of long. This maps to the id() function in python. Note that there is
no change for python caused by this and only code which is directly calling
Ops.Id from a statically typed language like C# or VB will be affected.<o:p></o:p></p>
<p class=MsoNormal>Assuming no major issues are discovered in this build, we
hope to rerelease it as our last planned IronPython 1.1 release, IronPython 1.1.2,
in several weeks. Please let us know if you encounter any issues as soon
as possible.<o:p></o:p></p>
